Specification of Letters Patent.

Application filed October l2, 1916. Serial No. 125,297.

To all whom t may concern:

Be it known that we, Jaco J. Gaufres and DAN O. GENTEs, citizens of the United Sta-tes, residing at Miami, in the county of Ottawa, State of Oklahoma, have invented a new and useful Slime Separator and Classifier, of which the following is a specification.

The object of the invention is to provide an ethcient and comparatively inexpensive apparatus whereby the maximum saving of slime or value bearing sand may be effected expeditiously, while at the same time a classification thereof may be secured to facilitate subsequent operations or treatments, accompanied by an effectual washing of the material.

Further objects of the invention will appear as the description proceeds, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 is a vertical longitudinal sectional view of an apparatus constructed in accordance with the invention.

Fig. 2 is a plan view of the same.

Fig. 3is a horizontal sectional View taken on a plane below the distributing and sizing screen.

Fig. t is a vertical transverse section taken in a plane through one of the settling tanks.

A feed board "or chute 10 at one end of the machine serves as a means for depositing the material upon a shaker screen 11 having a series or plurality of screen sections 12, 13 and 14 having graded meshes so that the finer particles are permitted to pass through the forward or first screen section l. 12, the particles of intermediate size through the section 13, and the larger size through the section 14, the residue being discharged upon the tailing chute 15, said screen being conveniently supported by means of links 16 from overhead hooks or hangers 17 carried by the frame 18.

Arranged respectively beneath the screen sections are settling tanks (three being illustrated in the drawings to correspond with the number of screen sections) 19, 20 and 21 having inclined sides diverging upwardly. The discharge from the screen sections, however, is not deposited directly in the settling tanks but rather in a concentrating funnel (one for each tank) 22 having inclined upwardly diverging walls and reduced toward its lower end or bottom which communicates through a T-fitting or connection 23 with, opposite nozzles 24 attached to said fitting and which project loosely and discharge into traps 25 having cut-offs 26. The traps 25 extend toward opposite sides from the sides of the tanks near the bottom thereof.

The screen is designed to be reciprocate-d or vibrated by any suitable means such as an eccentric 27 having its strap 28 connected with the screen frame by means of a pitman 29, and in order to secure the accurate deposit ofl the material passing respectively through the screen sections in the concentrating funnels to which they belong, deflectors 30 are provided, and beneath the deiectors are disposed spray pipes 31 adapted to be supplied with water from main 32, each branch pipe 33 being fitted with a controlling valve 34. Also overhead spray pipes 35, located above the screen, may be used under certain conditions, the branches 36 thereof also being iitted with valves 37.

In operation, the slime traversing the screen may be initially sprayed by means of the overhead spray devices, and as the material falls through the screen sections and enters the concentrating funnels, it is 'subjected to the action of the spray devices located beneath the detlectors to cause an initial or preliminary separation to facilitate the subsequent settling action.

The object is to secure the final separation by gravitation and for this reason the contents of the tank are protected so far as possible from agitation and particularly violent agitation, but in order that the action of the spray devices 31 may be effective, the perforated discharge tubes thereof are revolubly mounted in the couplings 38 so that the sprays may be projected in the most eective and desirable direction, controlled by the character or peculiarities of the material under treatment.

The head produced in each concentrating funnel by the weight of the contents thereof serves to force the liquid through the nozzles 211 into the trap 25 where the heavier particles are deposited, the liquid returning into the tank and rising to overflow into the troughs 39 supported by the partitions between the tanks which extend transversely of the machine and are provided at one side of the machine with outlet or discharge spouts 40.

.ln order to minimize the agitation in each tank and insure Athe proper settling of the values, there is arranged between the concentrating funnels and tank partitions, inclined fenders or baiiies 41 diverging upwardly in each tank tothe upper portion thereof. The fenders preferably extend downward to a plane below the lower ends of the concentrating funnels and are spaced from the floor or bottom of the tanks. Any overflow from the concentrating funnel, therefore, passes downward between the walls of the concentrating funnel and the fenders and reaches the interior of the tank at the bottom thereof from whence the liquid portion with the lighter' and undesirable admixture find their way upward between the tank partitions and fenders to the discharge troughs. The adjoining fenders of the companion tanks converge upwardly and have their upper ends connected and arched over the respective trough 39.

The collected values may be withdrawn from the trap by opening the gate orvalve 26 and when opened the discharge will affect all of the contents of the tank including of course the concentrating funnel.

`lVhat is claimed is rl. An apparatus of the class described embodying a settling tank, a trap extending to one side therefrom near its bottom, a hydraulically concentrating funnel within the rtank to overflow therein, and a discharge lower portion of the tank, a concentrating.

funnel within the tank having a discharge nozzle projecting into the trap, and a fender Copies of this patent may be obtained for between the funnel and wall of the tank for the downward flow ofv materials between the fender and funnel and for the upward flow of materials between the fender and wall of the tank.

a. An apparatus of the class described embodying aY settling tank having inclined sides, atrap at the lower portion of the tank, a funnel within the tank having inclined walls and a discharge nozzle at its bottom extending into said trap, and inclined fenders between the funnel and those walls of the tank between the sides, the lower ends of the fenders being spaced above the bottom of the tank for the upward iow of materials between said fenders and walls.

5. An apparatus of the class described embodying a settling tank having inclined sides and walls between said inclined sides, traps extending from said inclined sides near the bottom of the tank, a funnel within the tank having inclined sides, oppositely extending discharge nozzles connected to the bottom of the funnel and projecting into said traps, and inclined fenders between said funnel and walls for the downward flow of materials between the funnel and fenders and for the upward flow of materials between said fenders and Walls.

6. An apparatus of the class described having companion settling tanks with a partition therebetween, outlet means carried by said partition, and upwardly converging inclined fenders within the tank and having their upper portions united above the partition.

7. An apparatus of the class described em'bodyin companion tanks having a parti` tion there etween, a discharge trough carried by said partition, and upwardly converging inclined fenders within the tank having their upper portions united above said trough.

In testimony that we claim the foregoing as vour own, we have hereto aflixed our signatures in the presence of two witnesses.
